The Ethereum team proposed the EIL solution, aiming to make all L2 data usable seamlessly as if it were "on the same chain".

Odaily Planet Daily reports that the Ethereum Account Abstraction team has released a proposal for the "Ethereum Interoperability Layer" (EIL), aiming to make all L2 blockchains seamlessly usable as if they were on the same chain. Based on ERC-4337, EIL allows users to complete cross-chain operations with a single signature within their wallets, eliminating the need for cross-chain bridges or relays, while maintaining self-custody and censorship resistance, thus enabling a unified experience across the Ethereum multi-chain ecosystem.
